Richie Strahan weighs up his final three bachelorettes

RICHIE Strahan has a difficult decision ahead of him in the final week of The Bachelor.

Tonight's episode will follow the Perth native as he and the reality dating show's three remaining 'bachelorettes' travel to Bali for a final round of dates.

The romantic adventures will be followed by a final rose ceremony before tomorrow's grand final, when the 31-year-old Perth native will choose the woman he plans to pursue a relationship with off-camera.

Strahan tells APN the pros and cons he sees with each of the finalists.

Alex, 24, Victoria

"It is a big step to date a single mum, but in saying that it's just about being a good role model for the little guy (her son Elijah).  That's something I can do. There are a lot more qualities you look for in someone and I said to Alex it doesn't matter how many kids you've got. This process is not about anything else but you."

Nikki, 28, WA

"Nikki's an absolute sweetheart. I do have a lot in common with her and every time I sit down with Nikki we talk so in-depth about how easy our relationship is. Going into this week it was always going to be a worry that maybe it is just too easy with Nikki."

Olena, 23, NSW

"She's beautiful and she's quite young. She constantly challenges and confuses me. One day I was wondering if she actually liked me, then the next day I was like she definitely likes me. She's a really strong-willed woman who knows what she wants. When someone is closed off, though, you wonder if that will put restrictions on your relationship down the track."

The Bachelor airs tonight at 7.30pm on Channel 10.
