Ali Oetjen admits 'The Bachelorette' finale will be her 'absolute toughest week yet'

Season 4 of The Bachelorette Australia comes to an end this week and it seems viewers are in store for the most explosive episodes yet.

Taking to Instagram last night, this year's star Ali Oetjen promises fans are in for some thrills and tears, joy and heartache as she attempts to choose between her final suitors, Bill Goldsmith, Taite Radley and Todd King.

"It's going to be my absolute toughest week yet filled with blissful joy, wild adventure, heartbreak, gut wrenching empathy, shock surprise & last minute truths," the 32-year-old teased on Instagram. "One things for sure I do not give up, so I'll see you at FINALE!!"

Ali has previously opened up about how difficult the selection process was but she's not the type of girl to shy away from a challenge, especially now that she's got plumber Bill, 31, bank manager Taite, 28, and sales rep Todd, 26, to choose from.

"I kind of freaked out just before I was going to go in and thought, 'What if I don't find someone? Like, I don't want to be settling for anyone -- I want that Mr Right so I don't have to go through this all again," she said on The Kyle & Jackie O Show last month. "That was definitely playing on my mind, but that just all disappeared as soon as I met them all."

She also recently told TV Week that she's more than ready to build her life with someone, and she's willing to do whatever it takes to get to that point.

"I'm just a normal person looking for love," she told the mag. "In order to get there, there will be struggles, challenges, fear… but I've always been vulnerable, because I want to find love."

Buckle up because it sounds like we're in for a bumpy ride.
