I walked the track from Narcissus through Byron Gap to Lake Petrarch and then on to Cynthia Bay a couple of years ago. I would strongly recommend against beginners going there. It's not terribly hard for anyone used to off-track walking, but it could be exceptionally demoralising for a beginner.
The track is not officially close, but there is a Parks sign at the Cynthia Bay end stating that it is not maintained, and warning about how difficult it would be to use it and recommending to use alternative routes.
It's not terribly boggy (although there are a few areas of bog), but it is very overgrown, and in a few places rather scrubby, and in several places there is not visible track or foot pad at all (including several km of trackless button grass.
Even if you were to go in via the Byron Gap route (which is a beautiful walk - great forests!), you still need to take care. The foot pad is not clear in some parts of the forest, and you need to take care to look out for the track markers. Also, with the better camping (and nice beach) being at the southern end of the lake, you might want to walk right around the lake, and it is rather scrubby most of the way alongside the lake.
