Storm Coach Craig Bellamy is expecting a tough outing against Newcastle on Saturday evening as his side looks to secure their fourth consecutive victory.

Following back-to-back losses either side of their Round 17 bye, Melbourne have strung together consecutive wins against the Raiders, Broncos and then Tigers to currently sit in sixth place on the NRL table.

Bellamy is sure on Saturday his side won't be underestimating the Knights outfit who defeated reigning premiers the Sydney Roosters in their last outing at Hunter Stadium.

"We're expecting a really tough outing, we always do in Newcastle," Bellamy said.

"They are obviously playing at home and their last home game they beat the Roosters, that's pretty good form."

Consistency in selection and performance on the park has helped Melbourne string together consecutive victories, a factor that has pleased Bellamy along with a rock solid defence.

"We've just found a bit of consistency and our defence has improved," Bellamy said.

"The stats say it and it was, our defence was very patchy for the first 15 weeks which was a long time.

"We're certainly working hard on a lot of areas defensively and it looks like it's just starting to come through with results on the field.

"Having said that we need to keep working hard at it because we don't want to go into those old habits again."

The Knights will welcome back key playmaker Jarrod Mullen to their starting 17 on Saturday evening alongside the experienced duo of Kade Snowden and Akuila Uate who return from illness and injury respectively.
