We were vectored for the Visual approach 13R ZZZ.  (ILS Out of service).  We were cleared for the visual approach a few miles NE of ZZZZZ.  The aircraft was slowly descending through 2;200 ft. when we received a GPWS alert (obstacle alert) for a tower 1605 feet between us and ZZZZZ.  We immediately climbed back to 2800 feet. (Glide slope verification altitude). Climbing back to 2800 ft through ZZZZZ put us high on the approach. We configured quickly and ran checklist. Through 1000 feet we were still high on VASI but agreed must be stable by 500 in visual conditions. I realized through 800 feet we had not contacted the tower; tried to contact tower twice and realized we had the incorrect frequency; finally contacted tower passing 400 ft and was cleared to land.  Normal landing.The ILS was out of service. The pilot flying was new to the airbus (3 months) and not totally confident yet with the airplane. I let myself get a little complacent;  the weather was clear and I had flown many legs in the last 7  days. As pilot monitoring; I should have seen that we were drifting low outside ZZZZZ.  After getting high on the approach; should have requested vectors back around for a new approach to give us more time to reorganize.
Air Carrier Flight Crew reported GPWS alert on approach. Flight Crew corrected flight path and landed without incident.
