Show Us Ya Wac
Just a thread to see the different wacs out there with radio boundays/CTA marks etc etc. Doing up my second WAC now with all the info on so after any ideas colour scemes that work well 
I never do it.
A Sydney VNC and a Newcastle VNC covers most areas that I fly. As you appear to be based at Jandakot, try the Perth VNC, it covers the area N to Leeman, E to Kellerberrin and S to Busselton.
If I had to do it on a WAC, I'd use the same colours as on the VNC.

Some schools at Jandakot wont allow thier students to use the VNC!. Safer to put your own interpretation on a WAC apparently. 
Re That Chart-
Wot? No 'E'phemeral rocks??
Wouldn't be many other differences - would there?
Like the charts of 'old' in 'Up North'.....ephemeral lakes...ephemeral rivers....

I remember the Perth VNC had a huge number of errors when I was learning to navigate not too long ago (roads with towns and lakes on the wrong side). I also found that the VNC was too awkward a scale and too busy for any real use. I suppose that if you're not going to leave the VNC that it's OK but if you're going to cross over to a WAC then the sooner you get onto that chart the better.
Probably nothing wrong with putting lines on your WACs but definately do it in pencil as the boundaries change often enough. Also, don't make the lines so thick that you can't see or read what is under them, the cartographers (are map makers still called that?) have the luxury of moving the words and numbers around to accommodate the terrain and man-made lines.
Yikes, no way. The scale would make it ridiculous to cover the whole of Aus. Talk about over-navigating. Now putting airspace on WACs would be a capital idea, I think that in the US they're called sectionals. I only had to buy one chart when I was there and set to the same scale it covered almost four WACs using front and back and had airspace. No problems worrying about using out-of-date WACs with out-of-date heights for calculating LSALT (these also had grid LSALT). Would it really be so expensive to transition to these?

Or a better and simpler question, why don't they just produce VNC'S for the whole continent?

From memory....It was mooted many years ago to do just that.
Then the 'powers that be' decided that there would be too many 'airspace' amendments over relatively short periods of time, to keep printing new/amended WACs with Airspace, whereas the 'terrain' did not change much.......
However, 'twas thought by many to be 'worthwhile'....
Now, I still draw 'circles' on my WACs with freqs - if I can find them - and with LL's / CTA etc.
There was a time when 'someone' who is 'well known' to these forums, made the decision to 'drop' freqs from charts.....How 'handy' was THAT??
(Can't tell the 'great unwashed' the freqs closest to them - like they will only congest them...)

In a WAC, (Lamberts) straight lines are great circles which is how we navigate and the bearing change from A-B coincides with the change on the map.
A VNC would be sufficient for flying around on 30-40 miles navex type operations during your training but would be insufficient for the charter type flying you conduct flying 100-350 mile type sectors. You would have way to many maps also for a start!
Since VNC became available, I haven't had the need to draw on a WAC. I like what FTDK has done superimposing the airways over the WAC. The idea, working out terrain if things go quiet whilst IMC?
There are errors on the WAC re lakes on the wrong sides of roads etc. Some of the reasons schools give for not using it are hilarious (as are some of the other myths and legends). At least most others allow the student to actually work things out for themselves.
The rest of the world uses the 1:500 000 scale.
Whether it is mercator or lambert depends largely on whether the map is aligned North-South or East-West. It is the gnomic projection which has great circles as straight lines, not the Lambert.
Even so, do people really calculate great circle tracks for a 350 mile visual nav?!

eg Lake Fork-tailed Doctor Killer, which I discovered and named during my historic east-west crossing of the Tanami Desert in the FTDK in 2007.

The only charts that give full coverage across Australia are WACs and ERCs.
The sooner students start using these in conjunction with each other, the easier they will find their general flying and following on, their NVFR/IF.
Yes, the VNC will make it easier near the class C areas, but a PPL (or CPL) doesn't have a "VTC/VNC chart coverage only" endorsement so why not teach the correct methods from the start?

For those who find errors on WACs, why don't you contact airservices and notify them of the errors so they can be included on these amendments?
While we are at it, why the 
aren't airspace, danger, restricted areas, or grid MSA/LSALTs shown on WACs in Australia?
Its all computer driven these days and all it would take are a couple of extra clicks.
