There is bicycle infrastructure tagging (like cycleway=lane and even bicycle=yes) on a way (sometimes on a node, like amenity=bicycle_parking) and there is bicycle route tagging (like type=route, route=bicycle, network=rcn) on a relation. These are related (the former should be elements properly tagged in the latter, but if not, it isn't strictly wrong in some cases), but they are independent. I think what Andrew H. means by "regional defaults" is to allow the "laws in reality on the ground at the time of the data consumer consuming" combined with whatever tags there are in OSM to "rule," and "proceed accordingly." Yes, it is nice when everything is tidily tagged as it truly exists in reality and these infrastructure elements are "properly" tied together into a cohesive networks in a local, regional, national and international scheme, rendering in renderers that pay attention to this tagging and display appropriately. (And additional tags like cycle_network=* even go further to acknowledge what the specific network actually IS at a given level, too). OSM's data isn't like this all over Earth, but there are places (Europe, USA, some countries in Asia, Australia is getting better...) where it is more and more complete. Especially the complexities of international bicycle networks like EuroVelo at the network=icn level, combined with a rich mountain biking network (route=mtb, not route=bicycle, especially in the Alps and Germany, Switzerland and BeNeLux countries), Europe really shines here. But it does kind of fall down with implementation of cycle_network=*, but even that gets better (slowly), where the USA and other countries have "OK or even decent" tagging. Even more complex bicycle (route, especially) tagging has recently been proposed and is both underway and being restructured in newer tagging Proposals. So it depends on what you mean by "bike routing." Bike infrastructure tagging: that's what's being discussed, and it seems to be a fuzzy-one-way-vs.-another legal cleaving based on how laws get interpreted. A "solution" like what Andrew H. suggests can "kick the can down the road," though actually the approach of "let the data consumer make assumptions about this or that given being a particular region" isn't wholly wrong, either. There is an "effort expended (invested) equals value derived" equation to be understood here. Then, hit the sweet spot. Repeat, and pretty soon we're all winners with the data being a small investment (in correctness, because Oz agrees "this is how we do it here") and the value gained being "hey, bicycle routing around here makes a lot of sense!" It can be done. There's plenty of complexity here, but it can be teased apart, especially when there are pockets of both better and not-so-good tagging in a big country like you've got there, and you can say "this method is more complete, effecting an emergence on how we want to do this in Australia in a manner that is well on the way to being fully 'done' here." That way, a comparison "towards the better" (method of tagging that has already become established in that "neck of the woods") can show where there are deficiencies in tagging that need some boosting-to-better. Make a sub-project out of "bettering the deficiencies" and boom, biking is better. This works for anything in OSM, really. For footpaths and bicycles on footpath law, there's lots of how the rest of the world does this. Take a look at our wiki, fashion existing tags to work for Oz (or rework them so they do, if required) and agree amongst yourself. I know I'm both telling people what they already know and that it isn't always easy or non-messy to "agree amongst yourselves," but that's OSM. You gotta roll up your sleeves, talk to each other, agree, and tag accordingly. Not necessarily in that order.
