Deputy Nationals Leader Bridget McKenzie has bought a $2 million property in one of Melbourne's swankiest suburbs raising questions about her commitment to rural and regional Australia.

Records show Senator McKenzie, who styles herself as a gun-toting champion of the bush, settled on a near-beachfront two-bedroom cottage in Middle Park in the lower house seat of Macnamara this month. It is her second Melbourne property purchase.

Senator McKenzie's internal enemies nicknamed her the "Senator for Elwood" when it emerged she was living in Melbourne and not the bush, which the Nationals claim to represent.

Her parliamentary register now lists her Elwood property as an investment that she rents out. Her office said she lives in Wodonga. Confirmation was sought as to how long the Senator has been living there.
