After examing through the Eastern 106 timetable, It looks good, but the Sunday timetable sees a gap in services from Morley when there is a 67T due to depart Mirrabooka. After further investigating it turns out during these gaps whether its coincidentally or not, there seems to be at least a 60 or 48 or both departing during that gap period which means there is a guaranteed bus every 15mins between Morley and Perth on Sundays during the majority of the day! Quite good from my perspective and is possibly the most frequently and evenly spaced out served corridor in Perth now? Every 7 mins on weekdays with a double banking (i.e. 22 and 67 leaving at the same time) on some of the times during the day, and a 3 min frequency during peak periods excluding the 66 Limited Stop service which also provides even more capacity on Beaufort St! Saturdays is every 10mins till midday then every 15mins during the afternoon and now Sundays is every 15mins now too! Can't recall anywhere else in Perth with a corridor frequency of every 15mins excluding the CircleRoute!
