Can I get the same UK Visa twice if I use a different passport?

[janetj2]

I have dual citizenship and used my New Zealand passport to move to the UK with a Youth Mobility Visa in 2017, I only stayed there for one year. I now want to move back to the UK and have learnt that I am not going to be able to get a sponsorship visa like I originally thought I would.

I also have an Australian passport as I was born in AU. I am wondering I I would be able to apply for a Youth Mobility Visa with my Australian passport and be able to live and work in the UK on that Visa.
