If he is, the Prime Minister will no doubt have some flattering words about the first Chinese-born federal parliamentarian, who is now Liberal MP for the marginal Melbourne seat of Chisholm.

He might be more reluctant to admit that Liu's past has thrown up complex questions of identifying if and when, in relation to specific individuals, China's interference in Australian politics is potentially present and a risk.

On a benign view, Liu's story may be as simple as Morrison wants to paint it: a woman from Hong Kong who has overcome obstacles to get where she is. The ultimate have-a-go-to-get-a-go narrative.

In the political furore now surrounding her, Liu might be a victim of the growing worry about China's influence and interference in this country.

But legitimate and important questions have been raised about Liu. These revolve around two issues: firstly, her past connections to associations with direct or indirect links with the Chinese Communist Party, and secondly, the large amounts of money she has been able to raise for the Liberal party. While it has not been officially confirmed, it is known security authorities expressed concern about some of the people she assembled.

As a staffer (dealing with the Chinese media) of then Victorian premier Ted Baillieu, Liu was much valued as a fundraiser. Indeed, when she wasn't included in the travelling party accompanying his successor, Denis Napthine, to China, Baillieu made representations on her behalf, and she was added. It was said she needed to keep face with the local Chinese in Australia.

Liu has obviously been a highly effective networker. Those with concerns ask: did she, wittingly or unwittingly, get assistance from the Chinese authorities to facilitate that networking?

John Garnaut, a China expert who advised Malcolm Turnbull in the run up to the 2018 foreign interference legislation, has outlined China's approach to exerting influence, in evidence he gave to a US congressional committee last year. "The modus operandi is to offer privileged access, build personal rapport and reward those who deliver."

Outgoing head of ASIO Duncan Lewis warned of the broad danger in a speech at the Sydney Institute last week. "The current scale and scope of foreign intelligence activity against Australian interests is unprecedented," he said.

It was Liu's disastrous interview with Sky's Andrew Bolt on Tuesday, following an ABC story earlier that day about her previous associations, that turbo charged this week's debate about her.

Liu claimed memory lapses when pressed on her past links, and was all over the place when probed on her attitude to China's policy and the regime.

By the next day, the Prime Minister's office had ensured her previous associations and current views had been gathered into a neat statement, which she issued rather than delivered in parliament (the PM tabled it on Thursday).

But the interview had opened the floodgates for Labor and other critics.

Forced into a full scale defence of her, the government wheeled out the arguments that this was just a case of a "clumsy" interview, understandable given she was new to parliament, and that Labor, in pursuing her, was being "xenophobic" and "grubby".

Neither argument stands up.

The issues around Liu are about her connections, not a stuffed-up interview.

As for the government playing the race card, this was both wrong and foolish.

Concern about China's interference in Australian politics relates to the behaviour of an expansionist power. It's not based on race.

And in terms of tactics: has the government overlooked that one of Labor's attack dogs on the Liu issue is the ALP Senate leader Penny Wong, whose father is a Malaysian of Chinese origin? Wong would be unlikely to join the front line of a race-based exercise.

A better defence was Home Affairs Minister Peter Dutton's Friday line: "If the Prime Minister or I had concerns about Gladys Liu, we wouldn't be backing her the way we are."

While the Liu affair has had people reaching back to the case of former Labor senator Sam Dastyari, who quit parliament in the wake of a scandal over his Chinese connections, that's not a parallel.

Dastyari got money to cover expenses, made comments about China's activity in the South China sea at odds with his party's policy, and tipped off billionaire donor Huang Xiangmo that his phone was likely being tapped by security agencies.

In short, Dastyari was beyond doubt compromised. With Liu, it's a matter of questions to answer.

One new question is why, as reported by the ABC on Thursday, she did not include the key Chinese associations under scrutiny on her preselection nomination form, which asks candidates to list organisations "of which you are or have been a member".

In choosing Liu to run in the vulnerable seat of Chisholm the Liberals had someone they judged would do well in an electorate with a high Chinese vote. Labor also ran a contender with a Chinese background (born in Taiwan).

Having a candidate with a vast network brings political benefits but, as the Liberals are finding, the person can come with undesirable connections.

The Liu affair is the latest example of the need for parties to better vet candidates. This point was obvious from the citizenship crisis, and when some candidates were disendorsed after discovery of unacceptable social media posts.

Liu's parliamentary position is quite safe, on all we know at the moment. She was the pick and Morrison will stick. And if China had aspired to use Liu, MP, as an agent of influence, any such hope will have evaporated under the glare of the publicity she is now receiving.
