How long can you stay in UK as a non-resident under terms of DTA

UK National (born in UK) with Australia citizenship since 2005 Returned to UK for family bereavement and have remained for more than 1 year According to terms of DTA I consider myself non-resident for tax purposes (tiebreaker) as my 'centre of vital interests' is Australia Is there a time limit on how long I can stay in UK and still be regarded as non-resident for tax purposes according to this rule?

Hi

Please refer to RDR3 Statutory Residence Test as you have been in the UK for more than 183 days.

Thank you
