"While living in a remote community, I came to understand that connection to land is a fundamental part of the Indigenous identity," the Australian actor wrote on his Facebook and Instagram pages.
"Think about the past, have quality conversations. I SUPPORT YOU."
It comes after an anonymous note was posted at the local shopping centre in Fitzroy Crossing asking for the internationally acclaimed actor to support their cause.
NITV discovered the note and sought a response from Jackman while the note also became the centre of a social media campaign.
In his post, Jackman tags #ingetjetadoras - a reference to Broome documentary photographer, Ingetje Tadros, whose photos of children and residents from the Kennedy Hill community holding the note are at the centre of the social media frenzy.
"You said publicly that you only grew up after spending time in a remote Aboriginal community! Now the govt wants to shut them down," the note reads. "This week we will protest and the media will ignore us. We need your SUPPORT."
NITV can confirm that the message was written by a member of the Kennedy Hill community who has asked to remain anonymous.
Hugh Jackman spent time during his university years building houses in regional Aboriginal communities, an experience he said: “Really was where I think I grew up” on Canadian interview show George Stroumboulopoulos Tonight in 2011.
“I'd only seen images of problems, whether it was drinking, whether it was poverty, whether it was health issues, that was all I knew about the Aboriginal people.
"And I wanted to go back and say, hang on a second, you need to forget about those images, we need to go back and learn from the Aboriginal people."
The Barnett government has flagged the closure of up to 150 remote Aboriginal communities, a move that was exacerbated last week after the Prime Minister described living in remote Indigenous communities as a "lifestyle choice".
