In my part of the world the expression "Rear To Kerb" is used for this. Since all of the web examples that I've seen are prone to extreme link rot I'll just provide the relevant search query which will doubtless continue to yield a bountiful harvest.
Had this been a consistent policy in Australia then there would doubtless have been links to the signage and its meaning. However the policy on this is completely inconsistent whether within states (some of which, when last I checked, had a blanket ban on rear to kerb parking) or within towns, cities and regions within those states since some parking rules are enforced at local level, some (mostly no stopping prohibitions on motorways) at state level.
I don't believe that the motivation for enforcing rear to kerb parking has to do with a danger alert. Certainly a country town like Tamworth doesn't have a lot of those. It's because the driver has much more visibility when driving out of a parking space than when reversing out of them. If you're parked nose in and have a one tonne van parked on your left and an oversized "pickup truck" on your right the amount of visibility that you'll have of the traffic on the road when you're backing out is next to none. So the only thing you can do is back out reeeeaaalll slowly and cautiously until you can see something on either side, and hope that in the meantime no jackass with an "I own this road!" mentality comes down and smacks the living bejebbers out of your side panel.
The trade-off for this is that backing into a spot takes more time than nosing in, again because you need to get good visibility of the line markings and make sure that you go in between them, and judge when you're far enough back but not so far that your tail lights play kissy-kissy with the brick wall behind you. That extra time will obviously mean the possibility for disruption to the traffic flow.
Generally the local authorities will weigh up which is the bigger risk / cost, and assign parking accordingly. The down side of that inconsistency is that if you go for a drive in New South Wales you need to pay VERY close attention to the signage (whether it is front to kerb or rear to kerb, AND what the specified angle is) if you want to avoid a parking ticket.
Though in reality angle parking is probably less common down here that common or garden parking alongside the kerb.
