If you are considering a wrap, and want to use it long term, I would suggest a woven wrap rather than a stretchy wrap like the hug-a-bub. Woven wraps are much more supportive so can be used through to toddlerhood, most people find that stretchy wraps are fabulous for newborns but less supportive as the baby gets heavier and need retying/tightening as the weight causes the wrap to sag.

Some woven wrap brands to investigate are: Didymos, Storchenwiege, Girasol, Vatanai, Ellevil. Lots more as well, but these are some of the more commonly known ones. Depending on where in Australia you are different weaves suit different climates, Vatanai in particular are great summer wraps as they are thin and airy, Storchenwiege wraps are very supportive but are thicker and warmer. Girasols are somewhere in between. Didymos wraps come in different blends and weaves which vary in thickness and supportiveness. Generally speaking, the thinner the fabric or more open the weave, the less supportive, so finding the most supportive wrap that can still be worn comfortably in your climate is important (if you are in Melbourne, you are spoilt for choice. If you are like me, and live in North Queensland, it's summer wraps only).

For wrap information, google thebabywearer and baby carriers downunder - both are very good sources of information on babywearing. Wrapping is a little more specialised so most baby shops will not have any (let alone good) information. There are also a lot of choices (in both brands, styles and lengths) so telling you about woven wraps may not help your bamboozlement I'm afraid.

Ring slings: both Storchenwiege and Didymos also make ring slings from their wrap fabrics - these are excellent choices, especially if you intend to carry heavier babies - as they are supportive. Another good choice is the Maya Wrap Lightly Padded RS. Although some people find most ring slings comfortable, there are differences in the way that the shoulders are sewn and some people have preferences - if you are petite or narrow shouldered, for example, some shoulder styles will be more comfortable than others. Unfortunately, it is hard to say what will work for one person. If you (or your DH) have bad backs/shoulders, then a ring sling, or any one shouldered carrier for that matter, may not be best as your sole carrier, although it may be OK for short up and down type trips.

If you have the patience to learn to wrap, it is the most versatile way to carry your baby - there are many, many different types of carries. It is also the most comfortable and supportive way to carry, but there is a steep learning curve compared to other carriers.

HTH!
