Hey guys, I'm not sure if this is the correct subreddit to post this but I'm looking to either do the ABC or EBC trek in November. I'm coming from Brisbane and flights are anywhere from $1300-$1700AUD. I'm aware of the differences between the treks and the difficulty. What I'm unsure about is how much it will really cost without a porter or tour agency. It it realistic that I could do either of these treks for under $2500AUD or is this unrealistic. I'm happy to budget travel, including taking the bus to the trailhead etc. I'm aware of the travel logistics and everything, just need to know if I'm really underestimating the total cost of everything. I'm including the price of the flights into the cost.
