Anglo was set to exit Australia last year in a radical restructure, but announced in February that it would retain its local coal assets.
It comes after the company’s Australian operations delivered the best all-round business performance in their history.
"Our demonstrated restraint and resilience, compounded by a global commodities industry turnaround, has paved the way for Anglo American’s resurgence in Australia,” Anglo Australian country head David Diamond said.
"As we look to the future, Anglo American will build on its strong position as the third-largest metallurgical coal producer globally and remain a major mining business and contributor to Queensland and Australia long into the future.”
In confirming its permanence, Anglo will re-establish Australian people development programs, build organisational capacity and fill critical roles across the business.
The company will also re-engage with local communities, and recently invested A$150,000 in local initiatives, including providing funding for schools, hospitals, youth and local arts programs.
“Anglo American values its people and communities as a top priority,” Diamond said.
"We are wholly committed to creating sustainable operations that provide value and make a positive impact in our communities.”
Anglo has sold four Australian coal mines in the past 18 months, but retains its Moranbah and Grosvenor operations in Queensland.
