Applying to overseas SA roles - UK

I'm currently in Australia and am looking to work in the UK. I go to (what is the equivalent of) a target school (UNSW) in Australia and have worked in a boutique / MM bank during my time here. Wanted to know how feasible it was to apply for 2023 SA roles. Will I even have a shot at an interview given that most UK banks probably have never heard of my university and I won't be able to attend any networking events?

For what its worth I have a couple offers for grad roles in Australia (one of which has offices in the UK) but would much rather start my career in the UK.

I also have UK citizenship so work rights are not an issue.

Thanks
