SYDNEY (Reuters) - Australia's independent wage-setting body said on Friday it would raise the minimum wage by 5.75% from July 1, as families grapple with soaring living costs.

The lowest-paid employees will receive A$22.61 ($15.34) an hour from July 1, according to Reuters calculations based on the current rate of A$21.38. The decision from the Fair Work Commission would affect more than 2 million workers.

"The level of wage increase we have determined is, we consider, the most that can reasonably be justified in the current economic circumstances," said the Commission in a statement.

"In our consideration, we have placed significant weight on the impact of the current rate of inflation on the ability of modern award-reliant employees, especially the low paid, to meet their basic financial needs."

Some economists have feared that a sizeable increase could set a benchmark for other wage expectations and complicate the Reserve Bank of Australia's job of returning inflation back to 2-3% target range.

So far, aggregate wage growth - which accelerated to a decade-high of 3.7% last quarter - has lagged forecasts, with Governor Philip Lowe warning of upside risks to wages from weak productivty growth, rather than nominal wages.
