NSW is set to lose one of its 47 federal seats before the next election due to population changes, with teal independent seats in the firing line.
The changes could prove critical to the Albanese government's chances of retaining its two-seat majority.
But the Nationals put Mr Albanese's seat of Grayndler in the gun sights in their suggested redrawing of Sydney seats.
By splitting Grayndler voters between Tanya Plibersek's Sydney, Linda Burney's Barton, Tony Burke's Watson and Sally Sitou's Reid electorates, a new division could be created near Guildford.
Using the same methodology, teal independent Kylea Tink's North Sydney seat would also be turfed while the coalition would benefit from changes to shadow treasurer Angus Taylor's Hume and the Hunter seat of Paterson, narrowly held by Labor.
Teal independents such as Kylea Tink are in the firing line of a redraw of federal seat boundaries.
Taking Grayndler might have been turfed under Liberal Party plans if the party hadn't rejected outright any option that abolished the division.
"We are not aware of a division represented by the Australian Prime Minister being abolished in a redistribution process," the party said.
Instead, it suggested a merging of two teal electorates (North Sydney and Warringah) and the abolition of Education Minister Jason Clare's Blaxland seat.
A new seat would also be created and named after trailblazing aviator Nancy Bird Walton near the new western Sydney airport being constructed in her name.
Meanwhile, Labor would take Liberal-held Hughes in southern Sydney and then redraw most of western Sydney.
Rather than take North Sydney, the Greens suggest taking Liberal Paul Fletcher's northern Sydney seat of Bradfield, claiming it would minimise boundary adjustments for the remaining and surrounding divisions.
The NSW Redistribution Committee, which includes the Australian Electoral Commissioner, is seeking comment on the submissions.
A final decision is expected late next year.
