The main reason why a wallaby has a pouch on its abdomen is that, like all marsupials, the young are born very undeveloped after a gestation period that is much shorter than that of placental mammals of similar size. Upon birth, the joey must crawl to the mother's pouch where it attaches themselves to a teat. The teat swells in the joey's mouth, securing it in place so that it can continue its development within the safety of the pouch, much as a placental mammal protects its baby within its womb. The pouch is essential to the development of the young, functioning as the womb does in placental mammals.
The kangaroo's pouch is developed to carry around the baby kangaroo (called a 'joey') until it is large and strong enough to catch up to the mother or defend itself. There are many predators in the Australian outback that can easily prey on a young joey, and while adult kangaroos can defend themselves and jump away quickly from danger, joeys cannot. I have seen kangaroos in the wild and I can say that they often jump together in packs and are incredibly fast. A joey would be easily trampled if it was able to catch up.
It is only when the joey reaches at least 7-8 months old that the need to keep safe from predators is a consideration. Any joey dislodged from the pouch prior to this stands little chance of survival.

How does a baby wallaby get to the mother's pouch?
Essentially, the baby wallaby uses instinct. When a joey is born, its mother prepares a path for it from the birth canal to the pouch by licking her fur so it lies flat and in the direction the joey must travel. This is actually not to guide the joey so much as to stop it from drying out before it reaches the pouch. The tiny joey uses its claws and front legs to clutch the mother's fur until it reaches the pouch, where it attaches to a teat that then swells in its mouth. The joey stays attached there for a minimum of two months.
