i'm definitely not familiar with this accent
is that a narrow transcription? if you don't aspirate word initial plosives this might be irish or scottish. but not that many of those accents are non rhotic, so that's confusing
[av] for have seems french to me
but you use interdental fricatives so maybe this is a native speaker's accent after all
the t glottalization and non rhoticity seems british
the voiced fricative in [wɪð] is very confusing, especially since it's word final. i know the fricative might become voiced if there's a voiced segment afterwards but this is literally both word final and phrase final.
apparently australians and southern british ppl pronounce "not" the way you do
but the fact that you pronounce may like [mẽɪ] seems not australian to me
in conclusion, i have no clue. my very stupid guess is a type of british english i haven't heard before
anon if you see this, send me another one and let me know how close i was lol
