The mayor of the City of Canterbury Bankstown has sharpened his pitch for SBS to be based in Sydney's south-west after federal Labor vowed to look at shifting the broadcaster's headquarters from the lower north shore to western Sydney.

Opposition communications spokeswoman Michelle Rowlands said an elected Labor government would commission a study to investigate the feasibility of relocating the SBS from Artarmon.

The announcement on Monday follows repeated calls from local politicians and business leaders for the multicultural broadcaster to move to a western Sydney hub such as Parramatta or Liverpool.

"The feasibility study will examine the merits of addressing the inequality in western Sydney by utilising and leveraging the public's investment in the nation's multicultural broadcaster, the SBS," Labor said in a statement.
