Bass is one of eight federal electorates across the country being targeted in the Australian Christian Lobby's pre-election push to "influence" voters.
The ACL is running what it describes as a national grassroots election campaign, involving letterboxing, door-knocking and phone calls.
Bass is the only Tasmanian electorate to be a focus of the campaign.

One of the key issues the ACL is homing in on is the recent Tasmanian reforms to make the listing of gender optional on birth certificates. The Safe Schools program is also an area of concern for it.
Some of the other electorates being targeted are Petrie in Queensland, McMahon in New South Wales and Chisholm in Victoria.
ACL managing director Martyn Iles said Bass had been chosen based on its "demographic, marginality and candidates".
"We are particularly excited about the campaign in Bass, as it happened entirely off the back of the enthusiasm of our volunteers, who asked for resources and led the local effort," Mr Iles said.
"Bass was, however, always on our shortlist based on a demographic study of the seat and its marginal character.
"The campaign is highly targeted, aimed at demonstrating the impact of our campaign platform on a booth-by-booth basis."
Equality Tasmania spokesman Rodney Croome said the recent state gender laws had passed both houses of parliament and "the sky hasn't fallen in".
"The people of Bass have lots of issues on their minds this election and transgender law reform or Safe Schools are unlikely to be among them," he said.
"Voters have moved on, as shown by the unsuccessful attempt by one of the Liberal candidates [Kristy Johnson] in the recent state upper house election to win support by strongly opposing transgender law reform.
"The ACL is campaigning in Bass because the seat swings wildly from election to election and the ACL want to opportunistically claim credit if it happens to swing to the Liberals."
