Scott Morrison, the opposition's immigration spokesperson, made these remarks while delivering a speech titled 'Reasons to be optimistic about Australia's immigration future', Fairfax media reported today.
He argued that the country needed more than a "one-off snapshot of immigrants' English proficiency and follow-up tests could ensure language skills did not remain static."
"There is a great opportunity to have a series of barriers, if you like - a temporary entry (test), a permanent residence and potentially even citizenship, if people want to have that conversation," Morrison said.
"I don't think you rush into massive changes in that area lightly and I think you want to take a lot of advice on how you achieve that, but the principle, I'm saying today, is I want to see the English language and economic participation put at the centre of our settlement programs," he added.

He also declared that asylum boats containing illegal migrants which start off from ports in Indonesia would be turned back without seeking the latter's agreement.
His statement comes a day after four people were killed when their boat carrying 150 asylum seekers from Afghanistan, Pakistan, Iran and Iraq capsized off the Australian coast after starting its journey from Indonesia.
