"It's always growing, it's getting faster and faster, bigger, we can't keep up with it," Darug man Gordon Workman tells me.
"'It was called Blacks Town," Darug man and university lecturer Shane Smithers explains.
His plan to work "his" corner of Australia is soon disrupted, however, by those who already occupy the land: the Darug, an Aboriginal people.
On stage, Jamieson has played the Arrernte painter Albert Namatjira, in an accent influenced by German Lutheran missionaries, as well as the fictional Darug warrior Ngalamalum in Andrew Bovell's adaptation of Kate Grenville's novel The Secret River for Sydney Theatre Company.
Darug man Richard Green has taught his language in Sydney high schools for several years.
Two others not keen on going on the record due to ructions within the Darug Aboriginal Corporation, the body representing Darug voices, say they'd also consider backing a change if it were a Darug word.
As well as many Indigenous newcomers to the area, there's a Darug community, which, despite copping the brunt of the early days of white settlement, remains on country, retaining elements of language and culture.
To the Darug people of Blacktown, this bush is even more important.
The push for a name change is not the first bad publicity the council has generated amongst Darug people.
"For example, if you're in Darug country the main thing for a school is that you need to engage with the local [Darug] population and with the people who are the custodians of that land".
But some Darug people like Julie Jones, who I meet at the Mount Druitt festival, fear that the referendum is about race.
