No problem 🙂. There’s a group for under 50s (which you can join even if you’re over 50), ‘Breast Cancer Support for Under 50s’.
There’s ‘Breast Cancer Support - Australia’, ‘Australian Breast Cancer Support’, and another one which has a lot of members: ‘Breast Cancer Support - I Got This!’
The second and third ones I listed are Australian obviously, but I think it doesn’t really matter which one, as this question gets asked in all the groups, and if there’s lots of members there’s bound to be some from WA. Ask to join a couple maybe, post the question and I think you’ll get heaps of replies.
