Indi incumbent Helen Haines has spent almost 10 times the amount of her nearest rivals on advertising with a social media giant this election campaign.
Since February 13, Dr Haines has amassed $25,443 with 96 advertisements on Facebook as she seeks to retain the seat she won in 2019.
Nationals candidate Liz Fisher is next on $2797, Liberal Ross Lyman was just behind on $2737, while Labor Party nominee Nadia David spent just $409.
No other Indi hopeful spent any money on Facebook advertising for their individual campaigns.
Dr Haines has also been on the receiving end of several Facebook advertisements.
Liberal senator Jane Hume has purchased nine advertisements in May which have all targeted Dr Haines.
The advertisements claimed Dr Haines had voted primarily with Labor and the Greens or had offered no support to Albury Wodonga Health or to address inflation and cost of living pressures.
Senator Hume spent less than $200 on each of the nine advertisements, which are estimated to reach between 10,000 and 50,000 people.
Australian Christian Lobby spent between $4500 and $5000 on an advertisement titled "The Truth About Helen Haines" which started running on May 8 and has been viewed between 90,000 and 100,000 times on Facebook.
In Victoria, since February 13, the Australian Labor Party has spent $317,503, while the Liberal Party's Victorian division has spent $184,595.
