Very difficult Achievement this one. Watching 10 episodes of Home & Away is quite a painful experience to sit through and at 5 hours to get the achievement, well that's 5 hours of your life you will never get again. To help obtain the achievement, I would leave it playing on your XBone and go and do something more productive like painting a wall and watching it dry or going out, cut the grass and watch it grow back again for 30 mins, hope this guide helps.
