TN restricted areas will probably be active more often so it J251 is the standard route.
I beg to differ. Every time I have planned A461 AS to DN in the last 12 months I have never been sent around or via TN. It costs us $15 a track mile to operate, so how can ATC justify always sending us via TN every time on the off-chance that the RAAF is active AND BN Centre cannot vector us around them? What about after 1500 on Fridays until 0800 on Mondays? In Perth, we talk to the RAAF controllers at PEA who actively manage us thru their airspace. Why can't this happen in the NT, especially since you have radar coverage over and south of TN?
