Joseph and Anthony Gallenti – brothers and directors of The Farmers Mailbox.

Like many of you, we've been farming all our lives. We were raised in Kinglake West, Victoria, where we grew carrots on the family property and attended Yea High before both completing a certificate 3 in Horticulture. In 1995, our family decided to stop growing carrots and get into the business of growing instant lawn instead.

Fast forward 20 years and we're now proud owners of The Farmers Mailbox. We've recently taken over from Sandra and Jay Canning, who know we'll look after their customers well.

Our aim is to make this Australia's most convenient place to buy farm equipment online. There's also the retail store to look forward to – located in Whittlesea, the shop is due to open in May 2015.

We're always adding to our product line and putting great items on sale, so make sure you check the site regularly for updates and special deals.

Above all, we care about our customers and love talking to all our fellow farmers out there. Please don't hesitate to get in touch with any questions or queries you have.
