Yeah I can picture it. The non-rhotic R on its own doesn’t narrow it further, but there would be distinction within Australia based on the sounds of the “ea” part.

Off the cuff I can picture some Australians taking it more nasally at the top of the palate sort of yee-ah (think Steve Irwin), a more neutral yeehr with a hint of final r (but more clipped and mono syllable than an American accent), or even a yair that might push as far as yuhhh (heading towards a sort of hybrid of Californian Valley Girl and the posh British accent used in American media).
