As a confirmation, have you ordered PAL or NTSC SCART cables? As you're in Australia and are using a European set, you'll want to confirm you ordered PAL ones. This is more of an issue for folks in North America with NTSC, though, as we don't have SCART connectors on consumer television sets, so SCART cables are considerably rarer.
The cables are the same, but the signal being carried over the cable is different.
Regardless, I highly recommend a custom cable with coax wire from eBay retro_console_accessories, and I think there's a UK custom SCART cable shop out there as well. The official cables and knockoffs have severe problems with noise in the picture and audio.
If you can get your hands on an RGB monitor, I highly recommend getting one for retro gaming (240p and possibly 480i) along with the appropriate BNC and SCART adapters. The sharp picture, beautiful colors, and excellent contrast will make you wonder why most consumer CRTs were abysmal in quality.
I beg to differ. Composite video is abysmal in quality, but when you modify any SD CRT for RGB, the picture is fantastic. Here's some pictures of my modified Sony Trinitron, but the pictures don't do it justice compared to seeing it in person.

This TV wasn't even just free, but I had to take it to get that Sony because the guy wanted to get rid of them both. Turns out it's a fantastic set when modified. Again, the pictures don't do justice to how it looks in real life, photographing a CRT is difficult.

But beware - I have heard that there are TVs with a SCART port which do not support RGB. Those can probably be modified too
