Vic and ACT - rabidly Labor and suddenly... a redistribution that in every seat favours labor. Perhaps payback for the 15year late redistribution in SA?
No. You really should learn how redistributions work.
The population of the ACT has grown to the point where a third seat is justified. The ACT is safe Labor territory.
Several outer suburban Labor seats in Victoria are over quota due to population growth while Liberal seats tend to be under quota.

The top two seats in Victoria have an extra half a quota between them. That's MASSIVE.
The seven seats that are most over quota are outer suburban seats and most of them are Labor-voting areas. The Liberal exceptions are adjacent outer seats to the south-east on the Bass strait coast.
The Victorian seats are clearly malapportioned in favour of the Coalition. (You would probably call it a "gerrymander" though it technically isn't one). This is why Labor are gaining three notional seats in Victoria and the Liberals are losing two. (Although the renamed Corangamite would become a notional Labor seat, the notional margin would be a wafer-thin 0.1%).
The overall picture is to take a malapportionment that clearly favours the Liberals and rebalancing it back to the centre.
The bad news for the Liberals is that the current distribution in South Australia is also slanted towards the Liberals and the SA redistribution where one seat is to be abolished may see the loss of another Liberal seat.
The news in Queensland is better for the Coalition, where the quotas are more evenly distributed among the major parties. Queensland's boundary changes are relatively mild tweaking by comparison (all Queensland seats are within 7% of quota) and it's likely that no notional seats will change hands.
