I wouldn't be surprised if the piles are 25 to 30m long given that we've just installed 25m piles at Loganlea, which has probably similar geotech properties to Redcliffe i.e. mush & no rock founding level.

End of lesson
There's a concrete bridge down here,built in the early sixties, that is sitting on bales of wool ! The surrounding area is river sand and mangrove. Back in them days there wasn't concrete tecology and them trees weren't long enough to make the big piles...so they dug big holes and put in wool bales then poured the concrete over that. It's still good.
