Australia's attorney-general Monday defended a register meant to track the role of foreign agents in local politics, saying it was already changing behaviour despite only a handful of declarations.
Growing fears of political influence from foreign states, particularly China, saw Canberra pass a raft of new laws last year to curb potential meddling.
The Foreign Influence Transparency Scheme register was operational from December, with a grace period ending Sunday. But only nine institutions or individuals have so far declared their foreign links.
They include lobbyists such as former defence minister Brendan Nelson declaring his "foreign principal" as French defence giant Thales, and a 9/11 conspiracy theorist declaring interests for a US group.
Failure to register could result in penalties of up to five years' jail.
Porter said a recent flurry of departures of former Australian politicians from roles at Chinese-owned or linked organisations was proof the register was already having an impact.
"So it's likely that the register is also changing behaviour and contractual arrangements between individuals in the Australian political system," he told national broadcaster ABC.
Huawei told AFP that as a private firm, it did not need to register with the scheme.
Huang was a prominent donor to Australia's two major parties before he was blocked from re-entering the country last month -- with his permanent residency visa revoked and a citizenship bid rejected.
Huang himself has not signed up to the register.
Also missing from the public list is Chinese-Australian billionaire businessman Chau Chak Wing, who has denied links to China's Communist Party and last month successfully won a defamation suit against a newspaper that alleged he was a co-conspirator in a UN bribery plot.
"An ideal outcome, which is what we're probably heading for, is if we as a country can normalise transparency about this issue."
"Then I think we're well on the way to raising public awareness and well on the way to raising a public willingness for covert influence to be penalised," he told AFP.
