Adelaide - Jan 2009 - Weird supersatellite

I played in the super satellite today and it had a very weird structure.
It cost $450 to enter and this got you 3000 chips. Then as soon as you had less than 3000 you could buy another 3000 for only $100. At the break you could add-on 3000 chips for $100 but $150 got you 6000.
Level 1 is 25/50 so I rather thought the correct strategy was to rebuy immediately. However only 3 of us did this - so perhaps not. It did not do me much good since I got no hands at all.
Level 2 was 50/100 and I had to reload after my 99 reraise all-in of a family limped pot got called by the SB with TT.
On level 3 (100/200) I got my revenge on the SB when I had 88 vs 55. Shortly before the break I got very lucky when going all in with 55 vs KK and AJ and the dealer spiked me a 5 on the flop.
Then on the hand just before the break I make a ropey call UTG with A9 suited. There is a min raise and my nemesis calls so I call too. The flop comes K97 with 2 diamonds and I decided to see what the preflop raiser does - we check to her and she bets 600 and the BB calls. I am now pretty sure neither of them has a K so I bet the pot which will put the BB all-in. The original raiser folds and the BB calls with 9T. My hand holds up and after the add-ons I have 20000 chips.
We are told there will be 16 tickets to the main event (worth $3000) and there are 960000 chips in play - so looks like you will need to aim for a stack of 60,000.
The levels move quite quickly and I win a few lose a few and at the 3rd break (after Level 9) I have 22k and there are 30 players left.
Level 10 is 1500/3000 and after a raise with AJ that I have to fold when there is big action on a flop of AKT I have around 22k. I have been making a few all-ins and not getting called so when I have Q7 in late position and push again the big stack on the button thinks for ages and folds. Unfortunately the BB has AA and when I show I get some stick for having such a poor hand - I decline to argue and lose 10k in chips. Now I am struggling, and when I move all-in from the button with KQ after a min raise, I thought that he could may be lay down his A9, since it was costing him 6k into a 12k pot. However it held up and I was out.
On reflection perhaps I should have folded my Q7 but I don't think I had time to wait. We were down to 24 players but I don't think you can rely on 7 eliminations with an M of 8 and 25 minute levels....
