Upsetting world champions Australia would be the “best thing to happen to Samoa”, according to Matt Parish.

But the Samoan rugby league coach believes his underrated side have already achieved their Four Nations goal.

Remarkably win-less Samoa are still in the Four Nations final mix.

However, they will need to pull off something even more unbelievable to remain in contention – an historic win over the Kangaroos in Wollongong on Sunday.

Yet Parish reckons Samoa have already proven their point.

“Beating Australia, to register our first Four Nations win, would be the best thing to happen to Samoa,” said Parish.

“But in my opinion we have already proved a point.

“I think we have showed we are a creditable team and are more than worthy to be in the Four Nations contest.”

One of the great rugby league boilovers would help Samoa remain in Four Nations final contention but all Parish hoped for was a change of luck ahead of Sunday’s clash.

Samoa were pipped 32-26 by England in their Brisbane opener before New Zealand snatched a come-from-behind 14-12 game two win in Whangarei.

In both matches Samoa scored the same amount of tries as their opposition but were still denied becoming the first No.4-ranked team to register a Four Nations win.

“We are definitely overdue for some luck,” Parish told AAP.

“Hopefully we get the rub of the green this time.

“And if we could kick a goal that would be nice.

“But I just want us to be consistent.

“Consistency is not a word you would associate with Pacific Islander teams, that’s why it is so important to back up and play well again against a very good team.”

Samoa has only ever played Australia once before at the 2000 World Cup – it didn’t end well.

A Kangaroos side boasting the likes of Darren Lockyer, Andrew Johns and Brad Fittler ran amok in a 66-10 romp.

Yet Samoa will back themselves on Sunday against a depleted Kangaroos in danger of missing the final of a tournament for the first time since the 1954 World Cup.

Certainly their frenzied fans are behind them, judging by the letters from the Samoan Prime Minister that they have received.

Parish said his team saw the support for themselves during their pre-tournament camp.

“I think they realised the amount of support they had. Everyone in Samoa is talking about it,” he said.

“And the support we have received at the first two games has been phenomenal – there would have been as many Samoans as Kiwis at that second game.

“We’ve been blown away.”
