Find trusted waterproofing contractors in TAS

Looking for an experienced and appropriately qualified bathroom tiler/waterproofing specialist. My upstairs shower has a white acrylic base, and the bottom two rows of wall tiles sound hollow. I've recently noticed bubbling and peeling on the downstairs bathroom ceiling, possibly caused by water penetrating through the upstairs shower. I need someone to inspect the shower, identify whether the waterproofing has failed, and advise on the necessary repairs. I would also like an itemised repair quote following the inspection.
