Had to search this guy up to prevent eye rolling from the frequent fliers here

.
In September, I'm off to hit the majority of Oz (gonna kinda circumnavigate the continent), and most of that time will not be spent in cities. I don't plan on clubbing, though I'll certainly be taking occasional advantage of the pub hospitalities. I'll be rock climbing, surfing, and backcountry trekking the majority of the time, and we'll be in a 4x4 away from the populace for most of the trip. Duration should be about 4 months.
My plan was to bring my Strider boys, an MTL-SS and an SMF for the trip. I understand completely the idea of bringing something cheap so that you don't lose it or get it lifted, but my reasoning is that I got great deals on both of these knives (actually paid the same dollar amount for each of them), and that there is a good chance that I will be betting my life on these tools at least once. I would rather have a knife with me that I could trust to save my heiney should I need it to, and if I do lose one, I'll be severely annoyed, but not devastated, as I can replace them.
My question is, can I get these knives safely INTO and OUT OF the country without confiscation? They will be inside of my pack on the way in and out of the country and my bag will be checked, obviously, and not carry-on. If I lose a knife in the line of duty, I can understand, but I'll be LIVID if I end up losing it to some grubby government employee

. Do they X-ray bags when you arrive? If so, will they be upset by that big hunk of steel in there? Will I get the 5th degree, or will they just casually ask me why I have it, if they ask at all? I've tried to do my research, and have come up with this link:

It's a bit vague on the rules, but it seems that the two blades I was considering bringing are not expressly outlawed, and so I felt I would be alright. Again, I won't be carrying them in the cities.
Those of you in Australia especially, what are your thoughts on this matter? Think I'll be okay? I'm careful with my knives, and I always try to fly under the radar with them. I carried an MOD Mark V (pre-Blackhawk) through 6 Central American countries for three months and never had a problem, but that was the third world. I'm not sure what to expect in Uluru land.
Thanks in advance folks!:thumbup:
