Welcome to the Arms of Australia Inn Museum in the Nepean Valley at Emu Plains, NSW, Australia.

The Museum is administered by the Nepean District Historical Society (NDHS) Inc.

The buildings and grounds are administrated by a special 355 committee on behalf of Penrith City Council working closely with NDHS.

The  Inn was once a staging post for travellers making the trip from Sydney over the Blue Mountains to Bathurst and on to the goldfields. Built it two sections, the first in 1826, it is one of the oldest buildings in Penrith, if not the oldest.

Due to its colourful history, the Inn provides an interesting venue for tour groups, weddings photos, school tours and exhibitions.
The museum contains artefacts that were either part of evetyday life or were manufactured in the local area. The museum also has hundreds of photographs dating back to our earliest pioneers stored for future generations.

The Nepean District Historical Society meets at the Inn on the 4th Saturday of each month at 1pm and usually includes an interesting guest, speaking about local history. Visitors are always welcome.

The NSW Corps of Marines also call the Arms of Australia Inn  their home The members recreate the lives and times of the First Fleet Marines
