Former Canberra Liberals leader Alistair Coe tipped in more than $14,000 of his own funds to the party last year, federal donations data has revealed.
Mr Coe didn't give the party a cash donation, but $14,210 has been declared in "other receipts".
Donations disclosures released on Monday show big companies have spent millions on the major political parties in 2019-20, but no one has spent as much as Clive Palmer's Minerology company.
In the ACT the biggest individual donors were Forrest couple Craig and Eva Edwards, who donated $50,000 to the Liberal Party locally. The pair are regular donors to the party.
Sun and Sea Pty Ltd, a company connected to the Easi food delivery app and Tasting China restaurant in Bunda Street donated $18,888 to the Liberals. The party also received $17,600 from PricewaterhouseCoopers in other receipts and and declared rental income as $217,981 from its property manager LJ Hooker Commercial Canberra in other receipts.
The ACT branch of the Labor party received $57,500 from the Construction Forestry Maritime Mining Energy Union and $24,448 from the Community and Public Sector Union, the two most-influential unions within the local branch of the party.
As in previous years, the party's coffers were boosted by the party's investment arm, the 1973 Foundation. The Foundation directly donated almost $250,000 to the party, and $600,000 was transferred in "other receipts".
It means that in the ACT, the Labor party received significantly more donations than the Liberals, while at a national level the Liberals received more than Labor.
Overall, the Liberal-National Coalition received $59 million in donations, compared with Labor's $50.7 million.
The Greens received $19.7 million, and the Nationals $12.4 million. Donations to Pauline Hanson's One Nation party increased to $5.7 million, and Clive Palmer's party received just over $10 million.
Analysis from the Centre for Public Integrity shows 46 per cent of donations in the 2019-20 year came from just five donors, a statistic the centre says shows how a select few hold the most sway over political parties.
Clive Palmer's company Mineralogy was the biggest overall donor, giving $5,910,341 to political parties, mostly to Clive Palmer's United Australia Party.
Cardboard box company Pratt Holdings was the second biggest donor, spending just over $1.5 million.
Woodside Energy, Macquarie Group and the Australian Hotels Association rounded out the top five donors.
All of the Pratt Holdings donations went to the National and Liberal parties, while Woodside gave to both the Coalition and Labor party organisations.
But the Centre for Public Integrity's director Professor Joo-Cheong Tham, said the disclosure system is broken, with more than a third of donations still kept under wraps.
"The absence of caps on political donations has permitted a handful of donors to dominate the funding of political parties," he said.
"That the most significant level of government has the weakest political finance laws is a grave weakness of Australian democracy."
The release of the data has fuelled more calls for donation reform, as the total amount of donations received and the individual donors declared show the gulf between what is known and what is kept from the public.
While the Liberal Party declared $46,607,680 in receipts, there are only details of the source for $30,662,993. Of Labor's $50 million in receipts, source details are only disclosed of $36 million.
Of the Nationals' $12,427,565 in receipts, source details exist for $10,001,599.
According to analysis from the Australian Conservation Foundation, $38,777,998 of receipts have undisclosed sources across all the parties.
