Hi, can someone tell me where I can develop slide films in Sydney? How much is it normally?

I'm new to Sydney. I asked Camera House but they recommended me to go somewhere else directly for processing slide films rather than going through them.

I used to live in Hong Kong. There were professional labs for developing slides as well as negatives, for commercial and general personal use. The price was pretty resonable with excellent quality. Is there similar thing in Sydney as well? Thanks!!!
