Have you given any thought to Tasmania? It's an increadible state and not
overly large unlike the rest of the country. Take a look at
http://www.view.com.au/dombrovskis/ to get an idea of what it's like.

The issue for you is Australia is the world's largest island.  Most of it is
desert.  Most of the population lives within a couple of hundred kilometres
of the ocean.  We only have 20 million people.  What we call a mountain
range runs the lenght of the eastern side of Australia, 100 kilometres or so
inland, from there on it is basically flat, except for a few pockets in
South Aust, the Northern Territory and NW and SW Western Australia.

Much of the colours of the inland are reds, blues and browns.  At that time
of the year it is Veeeery hot.

Two weeks will give you a snapshot, pun intended.  You would need to spend 6
weeks because of the distances involved.  We think nothing of driving for a
couple of hours to get somewhere.

My suggestion is fly between states, don't drive.

If you fly into Sydney visit Kent St, west of the Town Hall, there are
several Bushwalking stores, such at Mountain Designs, Paddy Pallins that
contain extensive books on bushwalking destinations around the nation, there
is also the Youth Hostel Association HQ and a packpackers, that are full of
day trip activities, such as canyoning, abseiling, bushwalking, site seeing
etc.  These stores also have branches in the other capital cities

The point to consider in photographing our country in our Summer is the
harshness of light ie it is strong and washes out a lot of colour, forget
about photographing between 10am and 3pm unless you use a polariser and
shoot broad scenics.  The gum trees also emit a eucalypt vapour which
creates a blue haze, when viewed from a distance, which is why the Blue
Mountains are called Blue.  The further south you go the less an issue this
is.

If it was me.

Day 1  Arrive Syd
Day 2  Packpackers tour to the Blue Mountains and an evening walk on top of
The Harbour Bridge, if time permits.
Day 3  Sunrise shot of Sydney Harbour, featuring Circular Key, then fly to
Launceston, Tasmania, in the afternoon, about a 2-3 hour flight.
Day 4  Hire a Campervan and head in an anticlockwise direction around
Tasmania, starting at Sheffield then Cradle Mountain, stay in Caravan Park.
Visit the Wilderness Photography Gallery, a must visit.
Day 5 Day Hike around Cradle Mountain, with a dawn shot at Dove Lake.  Take
you winter woolies, it can snow.
Day 6  Drive to Strahan.
Day 7.  Take an all day cruise up the Franklin River and/or a scenic flight
from Strahan over the Central Tasmanian Highlands, it will knock your socks
off.   Weather permitting as the next landfall west of Tasmania is South
Africa.. it rains a lot, which is unusual for Australia as there has been a
bad drought on the mainland for some time. Both are a must do..
Day 8 Drive to Lake St Clair, if you have time take the ferry to Narcissus
Bay and back then onto Hobart.  Stay at my friends Hotel, The Astor Private
Hotel.
Day 9  If it is a Saturday, attend the markets at Salamanca, near
Constitution Dock, a great place to buy presents for family you left behind.
Drive to Cockle Bay, the most southern road destination in Australia, and
stay in the National Park campgrounds .
Day 10  Walk to the south coast of Tasmania, Lion rock and back, about a 6
hour round trip.  There are bushwalking campsites cut into the scrub in the
sand dunes if you want to do an overnight trip.
Day 11Travel to Port Arthur for the obligatory tourist visit to the penal
settlement, interesting views too.
Day 12  Drive to Coles Bay, Freycinet National Park
Day 13  Spend the day and walk over to Wine Glass Bay
Day 14 Back to Hobart or Launceston and fly back to the "Big Island", as the
Tasmanians say, say to Melbourne.
Day 15.  Fly Home

At the end of that you will be thoroughly stuffed.

If time is short drop Cockle Bay or Port Arthur, I would drop Port Arthur, I
still haven't been there.

Want to see what it is all like...?

Visit my website.  It was set up so I can share the wilderness with
others... this needs to be done.

Ok this is going to tak a while to write:

Ok Sydney to Melbourne is around a 9 hour drive (1 1/4 hour flight, cheap
flights are available for as low as $90 Aus $65 US)

Now if you drive the 9 hour drive, there isnt a lot to see apart from the
main highway.  But the Blue Mountains, North, Central & South Coast areas
are beautiful and all within 1 to 2 hours drive of Sydney. Sorry Otzi, but
I'm a but biased, I was born and bred in the Riverina and its boring as bat
sh.t LOL.  Actually it has some stunning Canola fields at the moment (oh and
BTW, the D70 struggles with the mass of yellow)  Obviously it goes without
saying that Sydneys Harbour is its jewel, and you will find plenty to shoot
around there, including plently of wildlife (even seen dolphins in the bay)

I wont go over the Queensland area as it was well covered by another poster.

Victoria (my home state):

North East of the State down to the Yarra Valley is mostly bushland, and
mountains very pretty.
Yarra Valley is one of Australias top wine areas.
As you come into the top of the populated areas of Melbourne you come into a
place called Healesville, well known for the Healesville Sactuary.  Here you
will find a lot of Australias natural fauna in there own environment.
(Check the link under my name and you will find some shots from there).

This area is the start of "The Dandenongs" a mountain range that flanks the
North to East of Melbourne, here you should find plenty of Aussie wildlife
as well as Puffing Billy, a very old steam engine with open window carraiges
that runs regularly through the mountains.

Heading south of there takes you down to what we call the Mornington
Penninsula (sp). this is another area full of wineries and stunning views of
the south east coast of Victoria.

As you start to head back up towards Melbourne, dont forget to head to
Phillip Island, well known for the Motor cycle Grand Prix, but equally well
known for its natural residents that come out at night, the Fairy Penguins.
and I believe Seals as well.

Cutting across from there brings you through Melbourne, Melbourne is a very
pretty and clean city with plenty to shoot, lots of great restaurants and a
stunning city skyline at night.

As you head West from Melbourne, there is a multitude of hidden treasures in
Victoria, if you stick to the main Highways, you will see nothing, but head
along the "Great Ocean Road" and you will see some of the most stunning
coastline you will ever see, try to time your trip so that you get to Port
Campbell before Dusk, because if you manage to get shots of  "The 12
Apostles" at the right time of the day, it will make your whole trip worth
it (once again, check the pics on my link, of the Apostles)

Directly north of there (about 2 hours) you will find "The Grampians" a
mountain range that juts out in the middle of nowhere, some stunning
opportunities there as well.

You will now head back towards Melbourne, you will pass so much on the way
including a small mountain called Mt Buangor, great wildlife and waterfalls
(waterfall shot in my pics) you will then pass through the Regional City of
Ballarat, here was the home of the infamous Eureka Stockade which was
basically a revolt by Gold miners back in the Gold Rush days, there is
plenty to see here, from a town fully recreated to represent those days, to
a show at night imitating the revolt itself.  Just a little further on is a
full size castle called Kryal castle, they do full on sword fights and its
made up to be just like medeval times.

Now one place that I suggest that you go to mainly because of the time you
will be here is a little Arty town called Daylesford, normally a pretty
little place, but at the time you are here, it is our Autumn (Fall), this
place explodes with colour, and its a great little place to stay and relax
for a while, they have natural mineral spas and plenty of galleries and
stuff to look at.  The food and cafe culture is alive there.

Thats all for Victoria (well if I put everything, this would be huge)

Tasmania

Tassie is about a 45 minute flight from Melbourne or if you like its an
overnight trip on the ferry (you can take the car)  Flights can be as cheap
as $45 AUS, the ferry has specials at times for around $99 + $10 for the
car.

The ferry stops at a port town called Devenport,  I could go on and on about
Tassie, it really is one of the most stunning places in the world but its
cooler than most other areas in Australia. Head west from Devenport takes
you to Burnie, a pretty little town, then head south to Queenstown from here
you cut across What is called Cradle Mountain, this is truly Gods Country,
stunning views, breathtaking.  You can also check out The Great Lake which
is not tht far from there.  Then you head South to the Capital of Tassie,
Hobart.  You can kick on from here to places like Port Arthur, there really
is so much to see and shoot, I could never put it all in a post.

You need to then head diretly north to return to Devenport to get the Ferry
back to Melbourne.  Make sure you stop in Launceston and check out yet
another stunning little Gem of a place.

All along the way you will see Heritage buildings that are nearly 200 years
old (Shene Stables on my site, is my friends place he purchased a couple of
years ago which he is renovating).  And countryside will be Green and lush
and full of Autumn colours.

Now I have only briefly covered 3 states and as you can see it would take a
long time to cover everything, I dont know much about regional South
Australia, or even Western Australia.  The Northern Territory is worth
seeing (Ularu (Ayers Rock) etc), but it is a few hours flight.

My email address is nmcs@bigpond.net.au, drop me an email if you want any
more info, I travel all over Australia and am lucky enough to have seen most
of it.

Cheers
