The Work Christmas Party HQ
End the year the way it should be ended: cold beer poured at the source, a table of proper food, and the whole team in one room. Book your Christmas function at Mash in Henley Brook, the Swan Valley venue just a short drive from Perth.
Spacious marquees, lush lawns and buzzing bars, indoors and out. As one of the Swan Valley's original breweries, Mash is a standout venue for a Christmas function in Perth's wine country, with room to breathe whether it is an intimate team dinner or a two hundred strong end of year blowout.
We have hosted work wind-ups, client thank-yous, staff parties and family get-togethers for over two decades. Award-winning beer is brewed on-site and poured fresh, the kitchen turns out hearty, share-friendly food, and the atmosphere does the rest. Dog-friendly, family-friendly, and open every day except Christmas Day.
December books out fast in the Valley. Only minutes from Middle Swan, Aveley and Bennett Springs, we are an easy trip for teams right across the area. Lock in your date early and let us tailor a package around your group.
