The lookout to be built in Cronulla Park will have a concrete curved face, sweeping views of Bate Bay and may include public art.
Tentatively called the Cronulla Community Lookout, it is among projects Sutherland Shire Council is planning to mark the 250th anniversary of HMAS Endeavour's arrival in Botany Bay and the meeting of two cultures.
The council has approved final concept plans for the Cronulla Park upgrade, costing more than $2 million, which is about $814,000 more than the original estimate due to extra works.
The lookout, with an adjoining garden, will be located near the top of the concrete stairs behind the north-western corner of the surf life saving club and public toilets.
"The lookout is proposed as a rest point along the Esplanade walk of particular benefit to people with limited mobility by providing the opportunity to take in panoramic views up and down the beach," a council report said.
It will be designed to meet the council's Disability Inclusion Action Plan, requiring design to achieve universal access where reasonable.
"The design of the lookout also includes a prominent curved concrete face over the beach which could be the subject of future public art either for 2020 or to recognise local surfing culture or other purpose," the report said.
The lookout will connect with a new bridge entrance to the rear of the surf club.
A top section of the Esplanade will also be upgraded as part of Cronulla RSL Club's plans to build a new cafe opening on to the walkway.
"The overall improvements in the precinct will be of benefit to the RSL Club by improving pedestrian connections to the cafe and an accessible path to the proposed lookout," the report said.
"The RSL has offered to contribute a total $145,000 toward the works."
The report said a principal aim of upgrading the public amenities was "to maximise their capacity while achieving an aesthetic result in keeping with the upgraded surf club building".
"Following recent representations from community users at the beach, council has revisited the functionality of the space and this has prompted a re-design for the female section of the amenities which will deliver only one additional WC cubicle, but provide showers and small change area," the report said.
"It is unrealistic to expand the footprint of the building to increase the overall size of the amenities area at this late stage of construction for the club."
The total cost of the park upgrade will be just over $2 million.
Contributions from the RSL Club and a state government grant will contribute $200,000.
