Featuring a greatly enlarged, fully air-conditioned and modernised product area including a walk-in coldroom, the new building at around 300 square metres is more than double the size of the old hotel bottleshop, and promises to continue the Porter family's renowned service to their patrons.

Busy travellers can now also enjoy the convenience of a two-lane drive through with mobile eftpos service.

Saturday's grand opening drew sizable traffic from 8am onwards, with plenty of attractions for the pre-Christmas crowds including a sausage sizzle, markets, face painting for the kids, sky divers and a live broadcast from radio River 949.

A popular highlight of the day was the Carlton Draught 'Beer Academy', a beer appreciation tour on wheels making a rare trip out from Brisbane.

Opening the new addition, Member for Lockyer Ian Rickuss paid tribute to the Porter family's longstanding support of their local community, not just through the ongoing improvements to their Hotel but in the less high-profile work of community, sporting and care organisations.

Things never stand still for long at Plainland, and hotel manager Michael Porter said the family was hoping to extend the pub in the new year, demolishing the old bottleshop to make way for an enlarged dining room and kitchen area.
