Jamaica's Women's World Cup to date has been a chastening experience, with coach Hue Menzies calling for extra funding to make his side competitive.

The Reggae Girlz have been smacked 3-0 by Brazil and 5-0 by Italy in their opening games, and face Australia at 5am (AEST) on Wednesday with virtually no chance of progression to the knockout rounds.

The Matildas aren't saying so, but will surely be licking their lips for a similar goal-fest against the world No.53s.

Jamaica is one of just a handful of sides not to score a goal and only Thailand, demolished 13-0 by world No.1s USA last week, have conceded more.

Menzies said his players, the lowest-ranked to qualify for France, had been served a reality check.

"I tell them sometimes 'we think we are great but when you come here on this stage, you see excellence'," Menzies said.

"That is what we have to be, we have to be in the environment to create excellence and it's unfortunate for them that we have to come here to learn."

Jamaica has one of the youngest sides in France, with a string of players picked up for the squad from the American college system with little international experience.

That they have struggled at their maiden tournament is no surprise, Jamaica has succeeded simply by qualifying.

After being abandoned by their national federation due to a lack of funding, the rag-tag side picked up a high-profile ally in Cedella Marley, the daughter of music icon Bob Marley.

Marley has acted as chief fundraiser and backer of the team in recent years, and they repaid her efforts last year by knocking off Panama on penalties to reach their first World Cup.

Menzies believes his country have the talent to return to the world stage in four years time with an improved performance if new support comes in.

"When you come into a tournament like this, obviously we are in a tough group, we are playing against countries that have resources, a lot of resources and we have to invest in our programme," he said.

"Hats go off to Italy ... we as a team have to take a page out of their book.

"We just have to as a country, as a nation, as corporate Jamaica, come and invest in football.

"We have the components and the natural athletes to (return to the World Cup)."
