The wombats gone through the snake 

Typically used when referring to project resourcing:
When a particularly stressful part of a project has been seen out, and resources will not be stretched in future months. In essence as the wombat passes through the snake, the skin is extremely stretched (similar to the metaphorical human resources). When the wombat has fully passed, the resources are not as stretched and more capable of dealing with new issues.

Person 1: Our resources are looking very slim next month
Person 2: I wouldn't be too stressed, I feel like the wombats gone through the snake, and we should be back to normal in a few weeks
