Currently, Sri Lanka has slid down to #6 in ODI rankings, #7 in Test rankings and #8 in T20 rankings.
In this backdrop, the mobile phone company which had co-sponsored cricket tournaments involving Sri Lanka in the recent past too, seems to be evading this tour, reports add.
The Australian team will arrive in Sri Lanka next week and the first Test match will kick off on July 26.
The Test series will be followed by a 5-match ODI tournament and two T-20 matches.
