Here is a website reviewing some Australian Photobook sites - I eventually went with Photobook Shop since they had good reviews at a good price. The website below also offers some great deals, a 20 page lay flat A4 photobook for under $30 seemed good value to me.

I only sent an order in last week so I haven't seen the results yet, but they do offer a free test print service so you can see what your image will look like. I'll let you know how it came out when it arrives.
I also had my best images for 2020 printed at Harvey Norman on their Fuji Frontier machine, A4 on
matte paper for $2 (don't get gloss, there is a warm colour cast). I'm very happy with it, I've always had good results from Fuji Frontier machines, worth checking out (IMHO).
