australia is a beutifull country. ive been there twice so far.
if i were you i would do a stopover either in hong knog or singapore. the flight is a killer otherwise.
sydeny is a lovely city lots to see lots to do.
the harbour bridge climb for one(i proposed to my missus on the top of the bridge )
the opera house
manly beach
the revolving restuarant.
a lovely place to be the bars also stay open till 6 in the morning then reopen at 9 in the morning:eyebrows:
never went to ayers rock so cant advise on that one.
as to up north then definatley have a stay in cairns, if you can dive the great barrier reef trust me you wont forget it. its amazing.
when we went to sydney we stayed with friends so i cant advise on places to stay either sorry.
if you need any more help then ask and ill see if i can help.
have a good one
