The Australian Conservation Foundation (ACF) has urged the Federal Government to make a "substantial reduction" to its skilled migration program in this year's Budget.

In its Budget submission to Treasury, the ACF says that if current migration levels continue they would contribute to a tripling of Australia's population by the end of the century.

The ACF argues that the projected population growth would make it more costly for the country to meet its emissions reduction targets, placing a high burden on "already stretched" urban infrastructure and ecological systems.
