Hey, thanks you guys. Info much appreciated and helpful. Looks like I'll be sticking to the slightly better accomadations for the wife's sake! I'm keen on going to the Seaventures platform. I've dived under it but have never set foot on it! Scuba Junkie's new resort could be a go though.
harakiri, noticed you're from Perth. I just came back a week ago from a holiday there. I've been thinking about diving Rottnest, hopefully next year. Have you dived there yet?
IF you are there to DIVE and not to enjoy the sand and beach, seaventures is for you. Its reasonably priced, dm's are sound, atmosphere is diver oriented and you get what you pay for. I was out there just 3 days ago for 3D2N and had a blast and I would highly recommend it.
But be aware, if you are expecting the 5star treatment, this is not for you. I liked it because:
1) no sand so gear was always clean and sorted
2) easy access to the boats using their hydraulic lift/ramp up and down
3) comfortable, if not simple rooms with a good/cold aircond, clean bathroom and room
4) Good atmosphere filled with divers who were there to dive. Good vibes
5) Food was good
6) Free dives (buddy system) below the rig anytime you wanted, including night dives up to 8pm for qualified/advanced divers
And I got my day out at sipadan on the 2nd day so no complaints...
I don't rate uncle chan's or billabongs because I don't rate their dm's nor their facilities which are not really catered for divers but rather for tourist.
But yes, you get what you pay for so don't expect much for your buck with either of them.
