Kokoda-Owers Corner or Owers Corner-Kokoda?

Just wondering if its a harder slog walking the Kokoda track from Owers.c- to- Kokoda or from Kokoda -to- Owers.c??
Also, it sounds like its hard to find accommodation in Goroka while the Sing-Sing is on. Would anyone know if it would be possible to camp out on a property somewhere in Goroka while the event is on?

Cheers.

south-north is apparently slightly easier because you don't have as mcuh height to climb, but either way is hard. In Gokoka you could try to contact the Kefamo centre just on the outskirts of town, they may still have a room, but if not I am sure they would let you camp. It is run by a bunch of nice catholics.

I did it in April from Kokoda to Owers Corner. I thought it was best to do it this way for several reasons, but I haven't tried the other way so can't comment too much.
However from my experience, it would be easier at Owers corner to try and get transport back to Moresby, where as if you wanted to fly from Kokoda to Moresby afterwards you be in for a wait. Even though we had charter flights booked, half our group spent an extra night in Moresby after the plane went AWOL after the first group were taken to Kokoda.
I found that doing it in this direction, you can sort ease yourself into it a more. Not necessarily the physical, but more the wet socks and constant mud. I found it drier at the start where as about half way, the river crossings (no bridge so must go through waist deep water) start to come into it. When this happens you get wet from head to toe and there is no chance of getting dry again.
Although the physical finish would be mostly flat (comparably to rest anyway) as you walk into Kokoda, I think the final climb up to Owers Corner is just what you need to make sure you are totally exhausted when you get to the top. It makes you feel the trip more when you've finished and you're feeling like you have for most days.
Not to mention the Arch at Owers Corner. PERFECT photo opportunity which means more once you have actually finished. I have many photos of grown men of all ages, teary eyed at the sight of the arch.
The reason our group did it this way was mainly for chronological reasons relating to the history. You start at Kokoda which the Australians were supposed to hold and follow the front line backswards to Imita Ridge as the diggers kept retreating trying to hold back to Japanese. We heard about each of the battles and significant sites as they happened so you can appreciate more day by day, what the diggers had been to by the time they got to a certain point.
Although in saying that, I think it would have been MUCH more emotional at Isurava memorial after walking for 6 days as opposed to only 2.
That's my experience and recommendation anyway. I guess it sort of depends what you want to get out of the trip. Whether you want all the history and everything or if your happy just to slog it out and get to the end.
Good luck and enjoy the journey.
