The latest series of Farmer Wants A Wife may see one farmer walk away single.

Fan theories have emerged online that Farmer Bert is 'bored' with his love interests and likely to leave the show alone. 

'Bert either has chosen just one lady and is going through the motions or is regretting going on the show, in my opinion,' one person wrote on Facebook. 

'I think he knows going on the show was a mistake but is trying to see it out. I'm sure he's going to pull the pin,' said another.  

'He shows no interest in anyone. Not sure if that's the case or he is just closed off to his emotions,' one more said.

'He's very closed off and just going through the motions with everyone,' someone else wrote.

'Bert does not appear interested in any of the girls... he is either painfully shy or has an interest elsewhere,' someone said. 'So awkward to watch,' yet another said.

The 30-year-old fruit farmer from regional Queensland has already had a suspenseful run on the season, after eliminating beauties April and Caity from his dating pool.

With only Karli, Caitlin and Lauren left to choose from, viewers have suggested that Bert has the strongest connection with Caitlin, a 27-year-old disability support worker.

However, in a shock turn of events, it has been reported in recent weeks that Bert ends up with no one and leaves the series as single as when he entered it.

One farmer has already left the show - but he did so for love. 

Farmer Dean declared his love for Teegan after calling her his soulmate and shocked the remaining women by sending them all home. 

He admitted he found a strong connection with Teegan and didn't need to move further in the experiment.
