How to play when 3rd is the same as 1st?

[KneeCo]

Not a big SnG player, but I'm currently working my way up the ladder in the Aussie Steps.

My question regards steps 3, 4 and 5, where 1st through 3rd all get the freeroll to the next level.

How should I adjust my play here? For instance, if I get about 40% of the chips in play should I just shut it down?

How can I expect others to play on the bubble? How can I best counter that style?

Thanks.
