The father of three Australian children killed on board Malaysia Airlines flight MH17 has taken indefinite leave from his job as head of Buxton Resources.

A brief statement from the Perth-based mining company on Monday said Anthony Maslin was taking personal leave from his job as managing director.

Mr Maslin and his wife Rin returned to Perth at the weekend from Amsterdam, where they had farewelled their three children on the ill-fated flight last Thursday.

The children, Mo, 12, Evie, 10 and Otis, eight, boarded MH17 with their grandfather Nick Norris so they could return to Australia from their European holiday in time to start school this week.

Their devastated parents flew home on Saturday and attended a public tribute for their children at Mo’s junior football club on Sunday.

The three children and their grandfather were among 298 people who died when MH14 was shot down over rebel-held eastern Ukraine.
