Tim Robards and Anna Heinrich are engaged

Australia's first Bachelor couple Tim Robards and Anna Heinrich have announced their engagement.

Taking to Instagram on Wednesday evening, Tim shared a snap of the pair, along with a caption reading: "LOVE made me do it!

"On the weekend... in a little dinghy... floating on a secluded river...I asked this amazing woman to marry me... she said YES!!! Woohoo!! #ENGAGED".

In the photo, Anna can be seen showing off her dazzling engagement ring.

Anna also shared a sweet couple snap which again featured her engagement ring, and wrote to her social media followers: "Officially forever #ENGAGED".

Tim and Anna found love during Australia's first season of The Bachelor back in 2013.

After celebrating their three-year anniversary last year, fans have been hoping Tim would get down on one knee and pop the big question sooner rather than later.

Addressing the speculation, Tim admitted last October that it "about that time" to drop to one knee.

"It's three years on, I think it's probably getting about that time," Tim told KIIS FM's Kyle and Jackie O.

"I know where I would probably go to get it. I know what she likes. I need to steal one of her other ones to find out the size," he added when pressed by Kyle about the ring details.

The handsome chiropractor also explained why he hasn't rushed marriage since appearing on the reality series.

"Coming off a show like that people love seeing the fantasy and the fairytale. For us, we just wanted to come out and make it real. You can't do what everyone else is telling you to do. It's probably why I didn't jump in after six months and say 'Okay let's do this.'"
