TCAS event over the bight today with two QF A330s

I do not sure how the airplanes work when there are two flights: one flight from east to west and another one from west to east.
The air and space is huge, they have both vertical and horizontal space, why don't they just split the lane similar to the highway on the ground. Ex: 10000m vertical and right lane for east to west, and 10500m vertical and left lane (500m horizontal from the right lane) for west to east. Then it solved the problem.

Collision avoidance system failed to activate on Qantas aircraft

Collision avoidance system failed to activate on Qantas aircraft - ABC News (Australian Broadcasting Corporation)

An interim report has found a collision avoidance system was not working effectively on one of two Qantas aircraft involved in an incident over South Australia last month.

An Airbus A330 flying from Perth to Sydney went close to another travelling from Sydney to Perth.

The collision avoidance system on the Perth-Sydney plane activated but the report concluded the same system did not activate on the other Airbus.

The report found an air traffic controller should not have given permission for one aircraft to climb.

Re: Collision avoidance system failed to activate on Qantas aircraft

They got closer than the ADSB data indicated, definitely a separation breakdown, and worse, close to a boundary!

Recorded data from the two aircraft showed that the minimum vertical separation was 650 ft at 1213:37, when the two aircraft were 4.1 NM (8 km) apart laterally. The minimum lateral separation was 1.6 NM (3 km) at 1213:51, when the aircraft were 870 ft apart vertically (Figure 2). At that time both the vertical and lateral separation were increasing as the aircraft were on separate one-way routes. The vertical and radar separation standards were re-established a short time later.
