In-ground pool lining

Hi,

I'm new to this forum so I hope I'm doing this post correctly. Please advise if it's not.

I've just bought my place. The inground pool has a marble lining that has deteriorated, to the point, that the lining needs replacing.

I'm looking for re-lining recommendations...ie. what type/kind of lining is best and any reputable companies to do it.

I'm in Brisbane.

I've read post here about dud companies and bad work because there is a lack of regulation protecting buyers, which is scary, because this is not a cheap issue to fix and it appears there are cowboys in this industry.

Any advice or recommendations is appreciated.

Thanks
