Australia's netball team sweated its way to a 47-46 win in its second match against the fiery Jamaicans in Kingston on Sunday (local time).

It's the third win in three days for the Australians after overpowering the home team 52-45 on Saturday, and the Jamaica 21U side 65-36 on Friday.

Australian coach Jill McIntosh is savouring every harsh lesson the side learns on its two-week training tour of Jamaica, as the Australians prepare for the world championships, starting in Jamaica in July.

Despite winning all their games so far, the Jamaicans have made the visitors work hard for their victories.

The Australians last toured Jamaica in 1998 and from McIntosh's experience, the locals are every bit as tough as they were back then.

"They are still offering a really big challenge," she said.

The Australians are hoping to get as much of a taste of the physically and mentally challenging Jamaican netball scene as they can.

One of their biggest challenges is keeping dry with the humid conditions creating an enervating playing environment.

So far, the Australians have maintained their champion form, however, McIntosh is leaving nothing to chance.

"We want to improve on each outing," McIntosh said.

"There's a long way to go before July. Unforced errors need to be reduced."

Joining the side are newcomers Cynna Neele and Natasha Chockljat who replace Eloise Southby and Jacqui Delaney.

Neele, a shooter for the Melbourne Kestrels, has begun climbing the steep learning curve of international netball.

"Cynna has had an initiation into open level netball," McIntosh said.

"I think she now appreciates how tough it is at the top and how tough you have to be."

So far, the only injury has been that of McMahon who sustained a minor ankle injury in the team's match against the Jamaica 21U side.

McMahon is expected to make a full recovery in time for the side's match against the Jamaican All Stars on Tuesday, a side made up of local club champions.

The third match against the national squad on Wednesday is still expected to be rugged despite Australia's good form.

The trip has certainly been a no-frills tour of the Caribbean island with the high local crime rate keeping the girls hotel-bound.

"We always travel together and we can't go wandering down the street down here," the coach added.
