Parramatta have described their finals exit as an "opportunity thrown away", but have vowed to learn from the experience and return a better side in 2018.

The Eels secured a top-four finish but went out in straight sets after their 24-16 loss to North Queensland at ANZ Stadium on Saturday night. The blue and golds led at half-time but were outplayed by a Cowboys outfit that again showed great resilience to earn a shot against the Roosters for a spot in the grand final.

Two of Parramatta's tries came from Cowboys kicks, while the other was a consolation touchdown after the siren. With the game in the balance, the visitors controlled possession and field position to consign the Eels to a 32nd year without a premiership.

"It feels like an opportunity thrown away. It's a tough pill to swallow right now," said Parramatta hooker Cam King.
