While in Australia, the MRF-D undertake a range of activities, combined exercises and training with the Australian Defence Force and regional partners. The MRF-D has grown in size and complexity since the first rotation of 200 US Marines through Darwin in 2012, through to reaching the milestone of 2500 Marines in 2019. It is now a highly capable force that provides significant opportunities to enhance interoperability with the Australian Defence Force. MRF-D composition will vary from year to year as a consequence of the activities being undertaken with the ADF and regional partners each year.
