Thanks, Philip: hard is correct- my question mark should have been a rather more explicit request for ID help!
When taking the photo(s) I was about 3 m away from the hawk but my sight was partially obscured by the fence, tap and odd bits of foliage and I hardly dared move (or breathe)  to try to get a better angle. (No binos, so this 12x magnification was only visible post hoc in the photo, not on the spot). I had very brief sights of it in flight both into and out of the garden - but both were primarily back views and the size/shape of the dangling Myna rather dominated my attention. Afterwards, I checked handbooks, COG photo gallery etc, and also compared (mentally) to 2 previous similar hawk sightings on kills in both Toms Cresc and Chaffey Cresc over the last few years...C Sparrowhawk is my tentative best bet, but I'ld welcome other opinions/suggestions.

The photo from Robin shows just how hard it can be to identify this hawk. Ordinarily you would say it’s a fairly good photo but nonetheless the really diagnostic features still leave me unsure. The size relative to the Myna suggests it to be a female Collared Sparrowhawk or male Brown Goshawk, so that doesn’t help much, the end of the tail doesn’t reveal its shape so no clues there, the brow ridge is small and that just suggests a CS, the beak is fairly small relative to the head and that too suggests a CS, although the toes appear sturdy like a BG but you can’t see all the middle one, so that is also unclear. I’d go 70/30 odds on it being a CS for those reason and most importantly because that is Robin’s suggestion and he saw it so got extra impressions than what I see, which is just that photo (which is much better than any photo I have ever taken of any hawk).
