"It is also an excellent chance to develop some team culture.
"There is little doubt that some swimmers from this group will be in the team for the Rio Olympics so we are looking to see who embraces the challenge this week."
Rush said he is expecting tight racing and with points for each event, it is important that every swimmer works hard for team points.
The team has had two light days of training at the Australian Institute of Sport in Canberra, which has been cleared by health officials after two international swimmers reported whooping cough two weeks ago.
Christchurch swimmer Matthew Hutchins, from the Wharenui club, is the only New Zealand swimmer who competed in the last biennial series in 2010. The Commonwealth Youth Games multi-medallist will be a clear favourite in the middle and long distance freestyle events.
The second test will be held tomorrow morning. The teams then travel by bus to Wagga Wagga in southern New South Wales for the next two tests on Wednesday night and Thursday morning, with the final two tests in Melbourne on Friday afternoon and Saturday morning.
