I used Priority One Plumbing when my drain got blocked. They charged me over $1000 for a total of about 1 hour's work to run a high-pressure water jet through my drain and a camera, which didn't clear the block at all. This was my first time using a plumber and I blindly trusted their pricing and advice. They then quoted me an extra $3000+ just for finding the location of the block. I instead got another plumber around, who found and cleared the block in about 20 minutes (it was a short distance in, at the bottom of the boundary trap) and charged me around $200; their minimum one hour fee. He said the block should have been located easily by the other plumber. I then asked Priority One Plumbing for a refund but they refused. I took the matter to my state's tribunal service (VCAT) and won a full refund but they still haven't pay. I would suggest people avoid at all costs!

Approximate cost: $1100
