We took the 1 day smartvisit card without transport. it was a really really good buy & we saved so much with tis fabulous card. we managed to do "the rocks walking tour", pylon lookout, sydney opera house tour & oz jetboating in the morningafternoon. We got ourselves by bus to darling habour by 4.30pm and did the sydney wildlife & sydney aquarium. the day was a bit of a rush but it was all worth with this heavily "subsidised" card! later, we had dinner & went to sydney tower too! please note that the last oztrek show is at 9pm.All in all, i will definitely recommend tis card to anyone,,,,,
