The experienced defender featured in every match for the Red & Black last season and joins the club from Norwegian side Avaldnes Idrettslag. 

Waldus played in 22 matches in the Topperien and starred in the club's recent UEFA Champions League campaign.

The 26-year-old has been included in this week’s extended squad set to travel to Dorrien Gardens to take on Perth Glory.

Wanderers have suffered back-to-back losses but are confident they can get the points away in WA.

Defender Caitlin Cooper said they remained upbeat following their most recent defeat, where they were shaded 1-0 by Brisbane Roar.

"We took a lot of positives out of the Brisbane game – we’re creating a lot of chances but just not finding the back of the net," Cooper said.

"The trip to Perth is quite a tough one but we’re fully confident we can get the job done over there."
